Real-time simulation of dissipation-driven quantum systems
Debasish Banerjee, Florian Hebenstreit, Fu-Jiun Jiang +2
We set up a real-time path integral to study the evolution of quantum systems driven in real-time completely by the coupling of the system to the environment. For specifically chos…
Dynamics of dissipative Bose-Einstein condensation
Stephan Caspar, Florian Hebenstreit, David Mesterházy +1
We resolve the real-time dynamics of a purely dissipative quantum spin or, equivalently, hard-core boson model on a hypercubic -dimensional lattice. The considered qua…
The inverse problem for Schwinger pair production
Florian Hebenstreit
The production of electron-positron pairs in time-dependent electric fields (Schwinger mechanism) depends non-linearly on the applied field profile. Accordingly, the resulting mome…
Schwinger pair production with ultracold atoms
V. Kasper, F. Hebenstreit, M. Oberthaler +1
We consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron-positron pair production in quantum electrodynamics (QED). For a setup in one spat…
Real-time simulation of non-equilibrium transport of magnetization in large open quantum spin systems driven by dissipation
Debasish Banerjee, Florian Hebenstreit, Fu-Jiun Jiang +1
Using quantum Monte Carlo, we study the non-equilibrium transport of magnetization in large open strongly correlated quantum spin systems driven by purely dissipative…
Real-time dynamics of open quantum spin systems driven by dissipative processes
Florian Hebenstreit, Debasish Banerjee, Manes Hornung +3
We study the real-time evolution of large open quantum spin systems in two spatial dimensions, whose dynamics is entirely driven by a dissipative coupling to the environment. We co…
